Hematoxylin Usage And Synthesis

Chemical Properties	light brown crystals or powder
Uses	Colorant in inks, biological stains.
General Description	White to yellowish crystals that redden on exposure to light.
Air & Water Reactions	Soluble in hot water, slightly water soluble in cold .
Reactivity Profile	Sensitive to light. .
Hazard	May be carcinogenic.
Purification Methods	Hematoxylin recrystallises from H2O (as trihydrate) in white-yellow crystals which become red on exposure to light and then melt at 100-120o. It has been recrystallised from Me2CO/*C6H6. It has been recrystallised as well from dilute aqueous NaHSO3 until colourless and is soluble in alkali, borax and glycerol. Store it in the dark below 0o. [Morsingh & Robinson Tetrahedron 26 182 1970, Dann & Hofmann Chem Ber 98 1498 1955, Beilstein 17/8 V 469.]
